Question

{36 x - 3y - 39 = 0,
{137 x + 2y - 35 = 0;
​

Answer 1

Ответ:

х=61/161; у= -8 73/161

Пошаговое объяснение:

36х-3у-39=0

137х+2у-35=0

36х-3у=39; 3у=36х-39; у=(36х-39)/3

у=12х-13

137х+2(12х-13)-35=0

137х+24х-26-35=0

161х-61=0; 161х=61; х=61/161

у=12×61/161 -(13×161)/161=(732-2093)/161= -1361/161= -8 73/161
